Who has the fastest shot? Agent Pea or Law Pea?

That's a good question. I think Law Pea shoots a little faster but Agent is more accurate at longer ranges and has to reload a little less often. It seems that way anyway, never tested it.

Law pea, no questions here. Agent pea has a cap on the firing speed, Law pea (and Z7 Imp) on the other hand fire as fast as you press the button. Unless you have fingers trained for rapid fire, you probably won't see too much of a difference though.
